Application
As agreed in the creation of this Training Package, applications for units transferred from the PUA00 Public Safety Training Package will be developed as part of continuous improvement plans, and taking into account the change in Unit of Competency format as detailed in templates for Streamlined Training Packages.
Prerequisites
DEFDV001B Dive using self-contained underwater breathing apparatus in open water to 30 metres .
SISOSCB307A Inspect and fill SCUBA cylinders.
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
1.Operate an HeO2 compressor/hand-booster pump | 1.1 Compressor and associated equipment are inspected for serviceability. 1.2 Protective equipment is fitted. 1.3 Leads and hoses are connected to the compressor. 1.4 Gas cylinders are charged to maximum working. 1.5 Operator level maintenance is performed on the compressor. 1.6 Compressor is de-serviced after use. |
2. Conduct dive operations | 2.1 CCBA (HeO2) is selected, inspected for serviceability, and fitted and tested (both out of water and in-water). 2.2 Dives are conducted using CCBA (HeO2) and dive contingencies are demonstrated. 2.3 Mid-water casualty handover is conducted between an HeO2 standby diver and an air standby diver. 2.4 CCBA (HeO2) is de-serviced and defects are reported in accordance with organisational procedures. |
Required Skills
This describes the essential skills and knowledge and their level, required for this unit. |
Required Skills |
conduct buddy breathing conduct ditching drills conduct lost buddy drills conduct unconscious companion diver drills conduct standby diver drills fit and check CCBA (HeO2) identify distress and illness in others at depth inspect and prepare CCBA (HeO2) monitor CCBA (HeO2) equipment and gauges recover and clear mask and mouthpiece refurbish CCBA (HeO2) post-dive |
Required Knowledge |
CCBA (HeO2) dive equipment characteristics and limitations CCBA (HeO2) characteristics and limitations dive physics dive physiology and medicine general occupational/diving safety awareness hazards of Heliox marine animal threats marine hazards oceanography relevant references and Australian Standards safe operating ranges for air-supplies standby diver responsibilities |
Evidence Required
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessment must confirm the ability to: arrange for others to check equipment conduct in-water checks handle non-functional equipment items prepare equipment for the dive including charging of cylinders maintain equipment during the dive refurbish equipment post-dive recover and clear mask and mouthpiece safely enter and exit the water appropriate to the launch platform, equipment and conditions switch from primary to the reserve air system implement contingency and emergency drills such as: ditching drills buddy breathing unconscious companion diver drills HeO2/air standby diver mid-water casualty handover drill. Consistency in performance Competency will be demonstrated over a minimum of 4 dives with the diver diving to a depth not greater than 60 m using CCBA (HeO2) in open water that includes the following requirements: oceans, seas, lakes and rivers day and night sub-surface conditions: a range of surface and sub-surface hazards current (0–2 knots) temperature (0 degrees +) visibility (0 metre +) Table 1 (below) outlines the minimum dives required by this Unit of Competency. Table 1

Context of and specific resources for assessment | Context of assessment Competency will be assessed in the ocean over a range of oceanic, diurnal and nocturnal environments, supported by questioning on shore or aboard vessels. When practicable, assessment should relate to the diver’s vocational focus. Specific resources for assessment Access to complete range of CCBA (HeO2) diving, safety and accessory equipment. |
